I am depressed. Last outing of the season, we get one time trail and then go right to first round.....I get my time trial, ran what I thought it would, line up for 1st round, and in the stage lanes I here what sounded like a fuse pop and then everything went south......
My Magnafuel pump split in half and had fuel poring out of it between the motor and the body. To make matters worse, it was wicked hot.....I think it killed a bearing and then seized. Won't know till I pull it, but it was hot as hell and fuel pouring out. Its the one with the built in filter, so I am very surprised....but also, not very happy.

Well, i’m sorry to hear about that. Especially during a round....but thankfully nothing else happened. That’s one of the things i worry about most. Fuel leak, causing a fire. I would also be pissed about a failure like that.

I noticed on there website these pumps are not for continuous duty, 1hr max, and I think, just like the cheap ignition system I had in the car, it cannot take the number of rounds I run this car or it builds too much heat...Two weeks ago, I ran three races, one on Friday night where I went four rounds, and two the next day going rounds and making it to the finals in one of those for runner up...I like to run the car, and it has to idle a little to get heat in it this time of year, so I would bet its just the duty cycle that killed it. Somtimes i even double enter the car, so I need somthing that keeps up with us bracket racers....Maybe this pump was a bad choice for me....Their 275 ran fine for me for years, but we were right at its limit hp wise....

Been more tales of woe on here regards Magnafuel pumps going bad than Carter has liver pills.
Thankfully, i never had more than 9 sec N/A cars that got plenty of fuel with a Holley black, and didnt need to waste money on high priced stuff like you are dealing with.
Feel sorry that happened to you.

If I add up today's mess, $45 entry fee, $20 food, and $30 in race gas on the ground wasted, and then the cost to get there 1/4 tank diesel, and what ever the fuel pump rebuild costs...I would bet it was all the racing I did the other week that got it to fail this week...Luckily, no fire....That thing was hot! I think its just the duty cycle, its not made for what we do with it.
The night I won, back on fathers day weekend, I went 5-6 rounds plus the two time trails, and the last run killed the ignition...Would not have made another run if I had tried....I think when the rounds start coming, they tend to be like round robin at the end...This puts a good bit of abuse on stuff...
I personally like the A1000 pumps for a lot of reasons. If I have to switch, it changes my whole fuel system and everything has to be re-done.
And tomorrow, I think I am ordering a Bulldog block.....I think we want to go faster...Seems his stuff is in some pretty high horse power cars now. Looking at a low deck 540 and maybe boost.....but that is another conversation.

Keep mounting your pumps sideways and this will continue to happen. BG400 pump user here, mounted upright, fuel bypass from pump to top of fuel cell with a homemade pipe dumping near the bottom of my fuel cell. Ohhh ya I run alcohol too.

Looking at a low deck 540 and maybe boost.....but that is another conversation. That isnt that many rounds to where anyone should have problems. Heck, i made 25 passes at the Moparty event In Bowling Green several weeks ago. I was in two classes, and they were consecutive. Had 8 passes made, 4 sets of back to back, before 1 in the afternoon, same the next day, except 10, instead of 8. Those were just time trials but each two laps were run within 10 minutes of each other, each day. Most races around here are 8 rounds with two time trials. Every race everywhere hot laps after the third or fourth round, unless its a huge field. If your having issues hot lapping in 4 or 5 round races, i would be looking into why. That wouldn't be normal

do you have yours wired into a relay? Birdtracker Yes, brand new relay after my "incident" a few weeks ago when I burned a lot of my wiring down to the ground in the trunk. I replaced pretty much everything, including the fuel pump relay and all the wiring because the alternator wire that fried, melted some of those wires because of proximity. Pump was not on at the time.
Keep mounting your pumps sideways and this will continue to happen. BG400 pump user here, mounted upright, fuel bypass from pump to top of fuel cell with a homemade pipe dumping near the bottom of my fuel cell. Ohhh ya I run alcohol too.
What do you mean, sideways?

I laid the pump down because Magnafuels tech told me it could be mounted upside down if needed. The way the pump is made if the seal goes out the bottom bearing gets washed out unless you catch it quick, no matter how it's mounted. Also there is a weep slot machined into the pump housing, unless the pump is mounted upside down or the weep hole up fuel wont make it to the armature.

A return from the regulator would probably cure this issue. Sorry for the lost time and agony! How would that have an impact? It's probably easier on the pump to return that shorter distance. This wasn't a duty cycle issue, hundreds of racers put these pumps through double.or triple entry weekends without issue. I've had weekends where I entered every class I could and made over 18hits. How old was the pump?

BG pumps were the "best" until they started to burn up quickly. Those with failures usually didn't read the instructions carefully. BG was very specific about the cell to pump line,5/8", and there must be enough difference in height between sump and pump so gravity always kept the pump wet. With little fuel in the cell, whether you forgot to check the fuel level between rounds or pumped the cell dry for winterization, that will quickly kill the pump. The fuel is the lubricant. When the pick up is uncovered for any reason, that starvation, no matter how small, starts the failure process. My Magna Fuel pump just started leaking at the track. Thought that it was just the line or fitting. Made a few more passes and the fuel pressure bounced inconsistently. Call it quits for the day. Sent the pump to MF and the washers, seals and bearings were shot. I was asked if the pump ran dry. I happened only once. Never again.
